After exchanging the segment display with a LTD040BUE-101A and I still did not get proper characters displayed. I checked the correct pinout of GPIO_OUTPUT_SEGMENTS and it seemed not to be...

Hi @DurandA, yeah, I noticed the possible confusion with the swarm of segment displays during my search as well. Was close to just using an OLED with I2C but it...

from the guide: [PicoFlyGuideV.6.2.pdf](https://github.com/Ansem-SoD/Picofly/blob/cc1099d6e9f659425b132fc73b9153fe07d605f8/PicoFlyGuideV.6.2.pdf) ``` ** RST is not connected *= CMD is not connected =* D0 is not connected == CLK is not connected *** No eMMC CMD1 responce...

Left outside capacitor seems not to be soldered properly. Do you have continuity checked all solder points? And flux residues should be cleaned off.

Maybe check youtube for "diode readings" for nintendo switch and measure these first?

I think, that there is no verify function with uf2 flashing. Therefore, bad USB connection or random hickups result also in bad programming.

Guess, you would have to tell the devs at least, on which rp2040 pins the LED is located for your clone device. Note, that nobody else besides the developers are...

I really wonder, if they got the pins wrong or if something else is off here... but here the bread crums to follow: from the original picofly code https://github.com/Ansem-SoD/Picofly/blob/main/code/usk/pins.h you...
